Embodiment Construction

[0028] figure 1 A prior art conventional compressor configuration is shown. The compressor 11 has an exhaust pipe 12 . The liquid reservoir 13 has a suction inlet pipe 14 and a suction outlet pipe 15 . The suction outlet pipe 15 is connected with the compressor, and is used as the suction pipe of the compressor.

[0029] figure 2 Shows the traditional air conditioning system structure. Such as figure 2 As shown, the structure of a traditional air conditioning system mainly includes a compressor 11, an accumulator 13, an oil separator 21, an evaporator 22, a condenser 23, a throttling device 24 and a series of pipelines. The suction inlet pipe of the liquid receiver 13 is connected with the evaporator, the exhaust inlet pipe of the oil separator 21 is connected with the exhaust pipe of the compressor, and the exhaust outlet pipe of the oil separator 21 is connected with the condenser 23 . The oil separator 21 is also connected with the accumulator 13 to deliver the retu...

Abstract

The invention relates to a compact of a liquid reservoir and an oil separator of a compressor, comprising a casing, a high and low pressure partition plate, an air suction inlet pipe, an air suction outlet pipe, an exhaust inlet pipe, an exhaust outlet pipe and a capillary pipe. The compact structure is characterized in that the high and low pressure partition plate divides the cavity in the casing into a liquid storing cavity and an oil separating cavity; fluid in the liquid storing cavity can exchange heat with fluid in the oil separating cavity through the high and low pressure partition plate; the air suction inlet pipe and the air suction outlet pipe extend in and are communicated with the liquid storing cavity; the exhaust inlet pipe and the exhaust outlet pipe extend in and are communicated with the oil separating cavity; and the high and low pressure partition plate is provided with an oil return hole which is communicated with an oil return hole on the air suction outlet pipethrough the capillary pipe, so that the lower part of the oil separating cavity is communicated with the air suction outlet pipe, and the air suction outlet pipe is communicated with the lower part of the liquid storing cavity through the oil return hole on the air suction outlet pipe.

Description

technical field [0001] The invention relates to a compact structure of a liquid accumulator and an oil separator for a compressor. Background technique [0002] All existing air conditioners are equipped with a liquid accumulator, which is used to avoid liquid shock when the refrigerant liquid returns, to ensure that the gas enters the compressor, and to improve the reliability of the compressor. The high-power air-conditioning system is equipped with an oil separator, which is used to separate the refrigerating machine oil in the compressor exhaust, reduce the possibility of oil accumulation in the heat exchanger, and improve the operating efficiency of the air-conditioning system. However, at present, the liquid reservoir and the oil separator of the air conditioner are set separately, which has certain limitations in improving the efficiency of the system, installation space and cost, and the characteristics of the two are not fully utilized.
